Microsoft is closing the work week with updates for two of its in-house developed Windows 8 apps. The Windows Store is now allowing users to download the updates for the Xbox Music and Xbox Video apps.

Unfortunately, there's no word on what's been updated in the change logs of the apps. Both the Xbox Music and Xbox Video pages are still showing the same patch notes that were made for their previous updates, both of which added a number of new features and improvements. We will update this post if and when Microsoft decides to release the change logs for today's updates.

Nokia has also released a new update for the Windows 8 Nokia Music app, which was first launched in early April. As with today's Xbox Windows 8 app updates, the Nokia Music app has no current patch notes on its Windows Store page. As we have reported before, the Nokia Music app allows users with a paid Nokia Music+ subscription to access and download music from a library of 20 million tracks.

Update: The new change notes for the Xbox Music and Xbox Video apps have now gone live and there are lots of changes and additions for both apps. The Xbox Music app has added support for semantic zoom to zoom in and out of a user's music collection, along with viewing which part of a user's music collection is on the PC and which music is store on the cloud. It also supports importation of iTunes playlists and more.

The Xbox Video app adds better access to information about actors and director, a way to view the video purchase history and restore previously bought videos and lots more.
